The RP55 modeling guitar processor is the easiest pedal to use. Musicians enjoy the multi-effects capability at the click of a footswitch. Equipped with 11 Amp Models and 20 studio quality effects with up to 8 effects which can be used at once for unimagined tonal possibilities. Just simply dial up your choice of amps and preset effects settings with no deep parameter settings. Enjoy professional tone with no hassles.

The RP55 uses our AudioDNA DSP chip to produce effects and amps that are studio-class. Plus 24-bit A/D/A conversion so that no frequency response is lost between inputs and outputs. Also included is a drum machine with 30 patterns and an easy-to-use 13-LED chromatic tuner.

This pedal is great. I owned one for about a year and then dropped it shortly after the warranty ran out. I am hoping to get a new one soon because for such a low price, this thing is amazing. It really opened up my sound.

What started as a simple string and pedal sales catalog has grown exponentially over the past thirty years. The early days were a time where catalogs didn't have much of a presence in the industry, but what began as a college dorm room operation grew rapidly. In 1986 we moved to a full product offering and 64-page catalog, which over the years has grown to 162 pages. Join the AMS family and get your free catalog now!
